TU RN-PLATE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 601,559, dated March 29, 1898.

Application filed October a, 1897.

To all whom it may concern.-

Be it known that I, IVILLIAM H. EMOND, a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Carriage Safety-Plates, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention is an improvement on the device patented to me December 29, 1896, No. 574, 313, and relates to improvements in safetyplates and turn-plates for vehicles, being especially adapted to vehicles of large size.

The objects of my invention are to render the safety-plate strong and compact, so that it will protect all the parts required, and also to facilitate the turning of vehicles of large size and to provide a beveled turn-plate whereby a strong bearing may be obtained at the greatest point of strain. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation, in part section,

of the gearing with safety-plate. Fig. 2 is a perspective view of the safety-plate. Fig. 3 is a top view of the turn-plate and axle made integrally or all in one piece. Fig. 4 is a sectional view of the turnplate centrally through the stud 6 and ridge-piece 8, showing the form employed when the axle is detached.

Similar numerals denote similar parts throughout the several parts.

1 is the upper plate, of metal, provided'with reach-plates 2, and on the front the head-block 3, bolted thereto.

4 is the turn-plate, secured to the forward axle by means of the clamps 5 and beveled on the under side and having greater thickness at the axle, where the greater strain comes, and making thereby a stronger bearing.

6 is a stud which forms the point of oscillation and is arranged in a suitable circular recess 7 in the upper plate 1. I may make this turn-plate integral with the axle, as shown in Fig. 3, or I may make it detachably applied to the axle, as shown in Fig. 4.

8 is a ridge on the turn-plate 4, which serves to strengthen it. 9 is the safety-plate, which is bolted to the upper plate 1 under the turnplate 4 by the bolts 1 11 is a rubber cushion upon the inner surface of the safety-plate 9, the same being covered by a thin plate of steel 12.

The safety-plate is triangular in form, with Serial No. 654,166. (No model.)

curved base, and has flanges 13 13 on either The upper plate 1 is provided witha recess 15 to allow the ridge 8 on the turn-plate 4 to' operate therein.

16 are bosses forming part of plate 1 on either side and beveled to allow of even bearing with the safety-plate 9 and through which pass bolts 10 10. I

17 are bosses on outer surface of safety-plate 9, which are made level to receive the nuts on bolts 10.

The sloping sides of the safety-plates allow the turn-plate to be made thicker near the axle, where the greatest strain comes.

It will thus be seen that the safety-plate with its flanges protects all the parts and allows a turn-plate to be used which can endure the strain of heavy vehicles.

Having described my invention, what I desire to secure by Letters Patent and claim is 1. The turn-plate, joined to the axle, hav

ing stud 6 and ridge 8, in combination with recessed upper plate 1, and the safety-plate 9, provided with flanges 13, bolted'to said upper plate beneath said turn-plate, substan-v tially as specified.

2. The combination of the turn-plate with means for attachment to the'axle, having stud 6' and ridge 8, with recessed upper plate having reaches 2, and stud-socket 7, the flanged safety-plate, bolts for securing the same, steel cover-plate 12, and elastic cushion 11, sub- 9c stantially as specified.

3. A turn-plate joined to the axle, having stud 6'and ridge 8, beveled underneath to' afford greatest strength at the point nearest the axle, in combination with the triangular 5 safety-plate provided with flanges sloping to the apex, and a recessed upper plate to which said safety-plate is attached by bolts, substantially as specified.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 23d day of' September, A. D. 1897.

WILLIAM H. EMOND.
